The "Miracle Mineral"

When is Asbestos dangerous?

Asbestos is dangerous when

it gets in the air and you

breathe or swallow it

TYPES OF ASBESTOS

Amphiboles

Serpentine

AMPHIBOLES

Amosite - brown

Crocidolite - blue

ƒShorter fibers

Amphibole Minerals

ƒStraight

ƒRigid (not flexible)

ƒVery Hard to Wet

SERPENTINE ƒLong, curvey fibers

Chrysotile - white

Serpentine Mineral

ƒFlexible fibers

ƒWettable fibers...

ƒwith amended water

MORE ABOUT ASBESTOS

Bundles of fibers which break apart easily

Fibers are microscopic

Very aerodynamic - float for days

Strong as steel

Resists breakdown from heat

Resists breakdown from chemicals

The best insulator

DEFINITIONS

Friable

Non-friable

FRIABLE ASBESTOS

Asbestos that can be

crumbled or pulverized

by hand pressure.

Friable asbestos is more

dangerous because the

fibers are more likely to

get in the air.

NON-FRIABLE ASBESTOS

Asbestos that

cannot be

crumbled or

pulverized by hand

pressure.

ASBESTOS CONTAINING MATERIAL - ACM

ACM is defined as a material containing greater

than 1 % of an asbestos mineral.

CATEGORIES OF ACM

Surfacing

material

Thermal

system

insulation

(TSI)

Miscellaneous

Materials

SURFACING MATERIAL

An asbestos containing material that is

sprayed, troweled-on or otherwise

applied to surfaces (such as acoustical

plaster on ceilings and fireproofing

materials on structural members, or

other materials on surfaces for

acoustical, fireproofing, and other

purposes).

THERMAL SYSTEM INSULATION (TSI)

Asbestos containing materials applied to

pipes, fittings, boilers, breeching, tanks,

ducts or other structural components to

prevent heat loss or gain.

TSI ACM contains more than 1%

asbestos.

MISCELLANEOUS

Any other type of asbestos containing

material.

Health Effects of Exposure to Asbestos

Asbestos Diseases

Asbestos can Kill You...

•When you work around asbestos, you must work carefully. Avoiding accidental disturbances is important.

•When asbestos is in the air, it gets into your body when you breathe and when you swallow.

When is Asbestos Dangerous?

•Asbestos is silent and deadly. You cannot see, hear, feel, taste, smell, or touch the small asbestos fibers that enter your body.

•It doesn't make you cough or sneeze, nor make you throat or skin itch.

•But if it is in the air, you can breath it. That's when asbestos is dangerous!

How do we know that asbestos can make you sick?

•We have been accumulating information for decades, tracking life and death histories of workers who's jobs involved exposure to asbestos.

•Over time it has become apparent that workers who were exposed to asbestos developed and died from diseases we now know are caused by asbestos.

Asbestos Diseases

Lung Cancer

Asbestosis

Mesothelioma

Other (GI) Cancers

How much asbestos is dangerous?

•There is no safe level of exposure to asbestos.

•But we do know that most diseases associated with the exposure to asbestos are dose-related.

•Asbestosis, Lung Cancer and Digestive System cancers are all dose-related.

•Mesothelioma is different. It appears to be incidence related, with dose not being much of a factor.

Latency Period

•The time between when a person is exposed to a hazard and when the symptoms develop from the exposure.

•The latency period is between 10 to 40 years

Your body has its own natural defense to help eliminate asbestos

But some of the tiny fiber can still pass through these defenses

Asbestosis

Scarring of the Lung Tissue

Specifically the Alveoli membranes

Lung Cancer

Cancer in the Lung

Mesothelioma

Cancer of the Plural Lining(s)

Pleural mesothelioma

Chest cavity

Peritoneal mesothelioma

Abdomen (belly)

Mesothelioma

•This is also the one disease that is only caused by exposure to asbestos.

•It is often referred to as the "Marker Disease" for exposure to asbestos sometime in a worker's past.

Other Cancers

Other Cancers can include:

Mouth, tongue, throat, voicebox, esophagus, stomach, intestinal, colon, rectal, and liver cancer.

Smoking and Asbestos Exposure•The Synergistic Effect - Multiplying Effect

People who work with Asbestos over a certain period of time will be required to have medical exams

These exams come at no cost to the worker

How is it determined if a material contains Asbestos?

First off, most materials are “guilty” until

proven otherwise by sampling.

Samples are sent to a lab for testing.

This sample must be collected by an MDH

certified Asbestos Inspector.

The sample is analyzed under a Polarized

Light Microscope (PLM) to determine content.

The lab sends out a report indicating if the

sample contains Asbestos and at what %.

Let’s see what we find in our room

1. Ceiling Tile

2. Ceiling Tile Adhesive

3. Vermiculite

4. Pipe Insulation on Riser

5. Floor Tile

6. Linoleum

7. Flooring Adhesive (multiple layers)

8. Paper between sub-floor and underlayment
